Strike Industries Enhanced Castle Nut with QD Mount – AR-15/AR-10

The Strike Industries Enhanced Castle Nut replaces the standard AR-pattern castle nut with a low-profile design that integrates a quick-detach (QD) sling swivel socket. This allows shooters to add a rear sling attachment point without installing a separate endplate adapter or bulky QD mount. The integrated QD socket sits flush when not in use, maintaining a clean receiver profile while providing a secure, rotation-limited sling connection when needed.

Machined from steel with a black oxide finish for corrosion resistance. Features a castellated design that accepts standard AR buffer tube staking. Installation requires an AR-15 armorer's wrench and follows the same process as a standard castle nut. Torque to manufacturer specifications and stake properly to prevent loosening under recoil.
